Can someone make the Water Quality ID thread again? It would be appreciated.

Not sure if you saw already, but here's the link for the ID thread.

So I'm coaching (assistant sort of) Water Quality this year. I've read the rules and all but I still don;t really understand what we are suppose to do. There's a test and it has three parts; testing, identification, and (I forgot the last one). So I guess my question is what are the main topics that I need my team to cover? Any help would be greatly appreciated

Was making a salinometer what you were thinking of for the last part? And studying all the indicated macroinvertebrates and what they look like in each stage of their life really helps a lot!

Yeah, I know that but what other stuff. I know we need to know the different types of cycles, pollutants, how to cure polluted water, but what else?

How do you guys tell the difference between Gilled Snail and Air Breathing Snail?
I get the whole thing about having/not having an operculum and left/right, but it's often really hard to tell with pictures. Any tips?

I know this sounds stupid, bit the picture of the gilled snail may be in water. In my experience the shells of gilled snails are slightly longer, thinner, and lighter colored.

For the gilled snail, does the larva look different than the adult? I can't find any pics of larva gilled snails. Will we have to be able to tell from both immature and mature what it is?

[Skink]

Mmmm, snails...


Yes, you should be able to tell which is which.
I found the following pretty face on a Quizlet game for this event. I'm not sure what the source was, so don't treat it as reliable yet. Anyone?


FOr whatever reason, this one seems a BIT more likely:


If a young gilled snail does look like that latter pic, you'll always be able to tell. That other thing looks like an insect.

Last year, the Water Quality disk worked wonders for me. It had everything we needed to know; cycles, macroinvertebrates, even a crude salinometer. I think they may be throwing out watersheds this year and changing it to estuaries. But it will be the same format, just different information.
That's my prediction; it may or may not be correct.

What's the difference between waste water and drinking water treatment?
